How To Handle A Web Table In Selenium Webdriver | Make Selenium Easy
Hello Folks,
In this post we will learn: 1. What is a web table? 2. Types of web tables. 2. Creating a demo web table using html. 3. Print all headers of a web table. 4. Retrieve and print number of rows in a web table. 5. Retrieve number of columns for each row. 6. Retrieve columns based on some conditions. 7. Retrieve last row of table. 8. Retrieve cell value using row and column number. 9. Retrieve column index based on column name.
10. Print all data from table.
What is web table?
A table is made of rows and columns. When we create a table for a web page, that is called as a web table. In HTML, table is created using
tag. Web table is a HTML structure for creating rows and columns on a Web page.
A web table can consists below parts:
- Header(s): It is created using
. Generally first row of table is header. We can retrieve header name and print them using below code:
// Printing table header of a web table assuming first row as header
List allHeadersOfTable= driver.findElements(By.xpath("//table[@name='BookTable']/tbody/tr[1]/th"));
System.out.println("Headers in table are below:");
System.out.println("Total headers found: "+allHeadersOfTable.size());
for(WebElement header:allHeadersOfTable)
{
System.out.println(header.getText());
}
Output: Headers in table are below: Total headers found: 4 BookName Author Subject Price
In above code, I am using index (/tr[1]) to locate first row of table. I am assuming first row in table will be header. Suppose, if we are not sure which row is header, then we can use below code:
// Printing table header of a web table assuming no information about header row
List allHeadersOfTable1= driver.findElements(By.xpath("//table[@name='BookTable']/tbody/tr/th"));
System.out.println("Headers in table are below:");
System.out.println("Total headers found: "+allHeadersOfTable1.size());
for(WebElement header:allHeadersOfTable1)
{
System.out.println(header.getText());
}
Output: Headers in table are below: Total headers found: 4 BookName Author Subject Price
2. Retrieve and print number of rows in a web table:
We can retrieve and print number of rows using below code:
// Finding number of rows in a web table. We need to exclude header to get actual number of data rows
List allRows= driver.findElements(By.xpath("//table[@name='BookTable']/tbody/tr"));
System.out.println("Total data rows found in table:"+ (allRows.size()-1));
Total data rows found in table:6
Since total number of rows includes header row, so we need to exclude header row from total number of rows to get actual number of data rows.
3. Find number of columns for each row:
Rows of a dynamic web table can have different number of columns. For example: Row1 has 3 columns while Row2 has 2 columns only. We can retrieve number of columns for each row using below code:
// Find number of columns in each row
List allRows= driver.findElements(By.xpath("//table[@name='BookTable']/tbody/tr"));
// We will start from 2nd row as 1st row is header
for(int i=2;i
tag.
Handling different scenarios of web table:1. Print all headers of web table:Headers of web able is also a row. Header is created using with |
